Customized intro text instead of first line of article

Dears,
I am searching for a way to put a customized text as the intro text on News (refreshed) where GK5-newspro is used. I have almost 1700 articles which not always start with a text that I need to show on the first page. On my previous template I used another module which let me show “meta data” section for that article as the intro text.
Please let me know how I can change the intro text default that is being showed by Gk5-newspro module on News Refreshed template.
Thank you,
M

I’m afraid that modifications such as this require extensive changes to the theme’s code; I do apologize but such large changes are custom work that are beyond the scope of our technical support.
